VoIP phone systems for small business let your team answer calls from desk phones, mobiles or computers. A practical guide for Australian businesses from Smart Phone Systems.
A VoIP phone system allows your business to make and receive calls using an internet connection instead of relying on a traditional landline. For small businesses, this can make phone communication more flexible, professional and easier to manage across office staff, mobile workers and remote teams.
If your business still depends on personal mobiles, old desk phones, limited call forwarding or a basic landline, a VoIP phone systems for small business can give you more control over how calls are answered, routed and followed up.
With the right setup, your team can use business numbers, desk phones, mobile apps, computer softphones, voicemail, call transfers, after-hours routing and call reporting as part of one hosted phone system.
Smart Phone Systems provides hosted phone systems for Australian businesses, including setup, number porting, call routing and ongoing support.
Significant benefits can be found by many industries once they implement a hosted phone system. Over recent months, we have helped Tradespeople, Retail Outlets, Hospitality and Accountants to enjoy these benefits.
What is a VoIP phone system?
A VoIP phone system is a business phone system that sends calls over the internet rather than through a traditional copper phone line.
VoIP stands for Voice over Internet Protocol. In simple terms, it lets your business make and receive calls using cloud-based phone technology. Staff can answer calls from desk phones, mobile apps, computer softphones or browser-based extensions, depending on how the system is configured.
For a small business, this means your phone system is no longer tied to one physical location. Your team can stay connected whether they are in the office, working from home, travelling between jobs or based across multiple locations.
How does VoIP work for a small business?
A VoIP phone systems for small business usually works by connecting your business phone number to a hosted phone platform. Incoming calls are then handled according to rules that are set up for your business.
For example, calls can be directed to:
- a receptionist
- a ring group
- a department
- a mobile app
- a desk phone
- a computer softphone
- a voicemail box
- an after-hours message
- an on-call team member
This gives your business more control over the caller experience. Instead of every call going to one phone or one mobile, the system can be designed around the way your team actually works.
For example, a call might first ring reception, then overflow to another staff member, then go to voicemail if nobody is available. Another business might use an auto attendant, where callers press 1 for sales, 2 for support or 3 for accounts.
Smart Phone Systems can help design this call flow as part of its hosted phone system setup process.
Why small businesses choose VoIP phone systems
Small businesses often move to VoIP because they have outgrown basic phone arrangements.
Common problems include missed calls, staff using personal mobiles, no professional greeting, limited call visibility, poor after-hours handling or difficulty transferring calls between team members.
A VoIP phone system can help solve these issues by giving your business a more structured and flexible way to manage calls.
Common problems a VoIP system solves:
- a more professional customer experience
- one main business number
- extensions for staff or departments
- better call routing
- mobile app access for remote staff
- computer-based calling
- voicemail to email
- after-hours messages
- call queues and ring groups
- reporting and visibility
- easier support for multiple locations
For many small businesses, VoIP is not just about replacing old phone lines. It is about making sure calls are answered by the right person at the right time.
VoIP vs traditional landline: what is the difference?
A traditional landline is usually tied to a physical location and a fixed phone connection. A VoIP phone system is more flexible because calls are handled through an internet-based phone platform.
This allows your team to answer business calls from different devices and locations.
For example, a staff member might answer from a Yealink desk phone in the office, another might use a mobile app while travelling, and another might use a softphone from their computer.
This is useful for small businesses that want to support hybrid work, field staff, remote workers or multiple locations without relying on personal mobile numbers.

What equipment do you need for a VoIP phone system?
The equipment you need depends on how your team works.
Some businesses still prefer desk phones for reception, administration, warehouses, clinics, workshops or high-call-volume roles. Others prefer mobile apps or computer softphones because they are more flexible.
A typical small business VoIP setup may include:
- a hosted phone system
- business phone numbers
- staff extensions
- desk phones where needed
- mobile app access
- computer softphones
- headsets
- call routing rules
- voicemail
- after-hours messages
- a reliable internet connection
You do not necessarily need a desk phone for every user. Some staff may only need the mobile app or computer softphone. Others may benefit from having both a desk phone and a mobile app ringing at the same time.
Smart Phone Systems lists softphones, mobile app access and Yealink handset options on its pricing page.
Can you keep your existing business number?
Yes you can, and generally speaking you would want to keep it. Part of our setup service is to help your business keep the existing business phone number.
This process is called number porting. It means your current phone number is moved from your old provider to the new phone system, so customers can continue calling the number they already know.
Number porting should be planned carefully to reduce disruption. As part of the setup process, Smart Phone Systems can help organise number porting and configure temporary routing if required.
You can learn more about the setup and porting process here: How We Set Up Your Hosted 3CX Phone System.
What features should a small business VoIP phone system include?
The best VoIP phone system for a small business is not always the one with the most features. It is the one that is configured around the way your business receives, transfers and follows up calls.
Useful features may include:
Auto attendant
An auto attendant, also known as IVR, lets callers choose where they need to go. For example: “Press 1 for sales, press 2 for support, press 3 for accounts.”
This can help callers reach the right person faster and reduce unnecessary call transfers.
Ring groups
A ring group allows multiple phones or users to ring when a call comes in. This is useful for reception teams, support teams or small businesses where several staff members can answer general enquiries.
Call queues
A call queue can hold incoming calls until someone is available. This can help manage busy periods and reduce the chance of callers being missed.
Voicemail to email
Voicemail to email sends voicemail messages to an email inbox. This can make it easier for staff to review, forward and respond to messages. Smart Phone Systems also has an article on voicemail to email with speech-to-text transcription.
After-hours routing
After-hours routing lets your phone system behave differently outside business hours. Calls can go to a recorded message, voicemail, an on-call staff member or another destination.
For more detail, see: How to Manage Phones for After Hours.
Mobile app access
Mobile app access allows staff to make and receive business calls from their mobile without giving out their personal mobile number.
This is especially useful for trades, mobile teams, remote workers and business owners who are often away from the office.
Softphones
A softphone lets staff make and receive business calls from a computer. This can be ideal for office staff, remote workers and users who spend most of their day working from a laptop or desktop.

Call reporting
Call reporting can help your business understand missed calls, call volumes, busy periods and how calls are being handled.
This is useful when you want better visibility than a traditional phone line or personal mobile can provide.
Is VoIP suitable for remote staff?
Yes. VoIP is often a very good fit for remote and hybrid teams.
Because calls are handled through the hosted phone system, staff do not need to be sitting beside a traditional office phone to answer business calls. They can use a mobile app, computer softphone or compatible desk phone from another location.
This helps businesses keep a consistent customer experience while giving staff more flexibility.
For example, a remote staff member can:
- answer calls from the main business number;
- make outbound calls using the business number;
- transfer calls to other team members;
- access voicemail;
- see call history;
- stay connected with the office phone system.
This is one of the main reasons small businesses move to a hosted VoIP phone system.
How much does a small business VoIP phone system cost?
The cost of a small business VoIP phone system depends on the number of users, extensions, devices, call routing requirements and any hardware required.
Smart Phone Systems publishes pricing for its virtual phone systems, including setup per extension, monthly extension fees, mobile app access and optional Yealink hardware. You can view the current details here: Smart Phone Systems Prices.
When comparing VoIP providers, it is important to check what is included. A low monthly fee may not always include setup, call flow design, number porting, training, support or hardware configuration.
For small businesses, the most important question is not just “What does it cost?” but “Will it help us answer calls properly and stop missing opportunities?”
When should a small business upgrade to VoIP?
Your business may be ready for a VoIP phone system if:
- customers are calling personal mobile numbers;
- calls are being missed;
- staff cannot easily transfer calls;
- callers do not know which option to choose;
- there is no professional greeting;
- voicemail is hard to manage;
- after-hours calls are not handled properly;
- remote staff need better access;
- you are opening another location;
- you want reporting and better visibility;
- your current phone setup feels messy or outdated.
A VoIP phone system can bring these pieces together into one more professional and manageable solution.
